Sintering A Step Between Mining Iron Ore and Steelmaking By Alison Cestari The USGS defines iron ore as a mineral substance which when heated in the presence of a reductant will yield metallic iron Fe It almost always consists of iron oxides the primary forms of which are magnetite Fe3O4 and hematite Fe2O3
